Abstract
LIKE the myriapods, the apterygote hexapods fall into four classes, whose interrelationships are still far from clear (Manton, 1970, 1972). Of these four, two have been severely neglected by embryologists. The embryonic development of the Protura remains entirely unknown, while that of the Diplura (e.g. Campodea,Japyx) has been the subject of only a few superficial investigations. Grassi (1885) reported on the embryos of Japyx, limiting his observations essentially to the fact that J. solifugus has a dorsal organ. The development of Campodea staphylinus was examined briefly by Heymons (1897a) and then in more detail by Uzel (1897 a, b, 1898). Uzel's work is informative on the general course of embryonic development, but can no longer be regarded as satisfactory in respect of questions of internal development, especially of the mesoderm. More recently, Tiegs (1942b) made valuable observations on the germ band and dorsal organ of Campodea fragilis, but his intimation of further work to come was, unfortunately, not to be fulfilled. The classic paper on dipluran embryology, therefore, still remains to be written.
